A tool for the analysis of reconfiguration and routing algorithms in irregular networks

Abstract

High performance interconnection networking is one of the most active research fields in the area of communications. Their quick development has been increased by the interest in using multiple workstations in parallel processing. These local networks use ideas that are already successfully applied in parallel computer interconnection networks. However, their more flexible and dynamic environment exposes new problems, such as topology configuration and message routing, which are difficult to solve with the current methods used in regular networks. Therefore, it is advisable to apply tools that help the researcher to develop and verify the behavior of new algorithms for these new networks.

Nowadays, the RAAP group (Redes y Arquitecturas de Altas Prestaciones, High Performance Networks and Architectures) of the University of Castilla-La Mancha is working in this way. In this paper, we present a software tool developed by the RAAP group with the aim of helping in the research. It does not try to simulate the communications within the network (where a long computation process would not be able to guarantee none of its properties) but to analyze its behavior, through the channel dependency graph. The result is an agile and practical tool that provides conclusions in a quick and reliable way.
